Band structure of 184Ir

Abstract

States of 184Ir, excited through several (HI, xn) reactions were studied using in-beam γ-ray and conversion electron spectroscopy techniques. A new high-spin level scheme, comprising three different rotational bands is presented. The negative-parity ΔI = 1 ground-state band is the most complete example of the semidecoupled \\ ̃ gp h 9 2 ⊗ v ̃ i 13 2 structure, in a prolate deformed situation, known to date. The other two bands are the doubly decoupled \\ ̃ gph 9 2 ⊗ v ̃ 1 2 − [521] and a ΔI = 1, \\ ̃ gp 5 2 + [402]⊗v i 13 2 based structure of the compressed type.
